View source for Good regulator theorem

The term '''good regulator theorem''' (lowercase) refers to the same result as [[Good Regulator theorem]]: the theorem proved by Conant and Ashby that every good regulator must be a model of the system it regulates. The lowercase usage is common in the broader cybernetics literature, where the theorem is treated as a general principle rather than a formal result.

In this usage, the good regulator theorem is connected to [[Ashby's law of requisite variety]] and to [[Stafford Beer]]'s viable system model. The lowercase form emphasizes the theorem's status as a design heuristic rather than a mathematical proof. What the lowercase tradition adds is the emphasis on practice: the theorem is not merely a statement about information but a guideline for building systems that can regulate themselves, from thermostats to organizations to ecosystems.
